How to Use the FieldAware MCP in Pydantic AI

Q: How do I configure the FieldAware MCP Server in Pydantic AI?

Use the MCPToolset class pointing to your Vinkius HTTP endpoint. Pass this toolset directly into your Agent constructor to expose all twelve tools safely.

Q: Can I use Pydantic AI to validate FieldAware quotes?

Yes, when you call listquotes, the response is parsed through strict Pydantic models. This ensures your agent only processes valid pricing and expiry dates.

Ensure type-safe field service automation by connecting FieldAware to your Pydantic AI agents.

Perplexity

Type-safe job execution with Pydantic AI

The `create_job` tool requires strict parameter validation before any work order is dispatched in FieldAware. This MCP Server enforces these schemas at runtime, catching missing addresses or invalid dates before they reach your FieldAware account. If your Pydantic AI agent attempts to pass malformed data, the framework triggers a validation error immediately. This prevents corrupted database entries and ensures your field technicians receive clean, actionable assignments.

Validated financial reporting

The `get_invoice` tool pulls FieldAware billing data that is instantly validated against Pydantic models. Your Pydantic AI agent parses complex financial records using `list_invoices` without risking silent parsing errors or hallucinated numbers. This strict validation makes this MCP Server setup ideal for automated bookkeeping systems. You can trust that the invoice totals, tax rates, and line items match your actual ledger exactly.

Structured asset and quote tracking

The `list_assets` tool returns equipment records that map directly to your local Pydantic AI models. Your agent can safely inspect hardware serial numbers and service histories retrieved via `list_quotes`. Because Pydantic AI is model-agnostic, you can swap your underlying LLM while maintaining identical validation logic. Your asset management pipelines remain stable even if you migrate from Anthropic to OpenAI.

Setup guide

Set up FieldAware MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "fieldaware-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to FieldAware tools.",
)

result = await agent.run("List recent FieldAware transactions")
print(result.output)
